Letters Patent No. 70,222, dated October 29, 1867.

IMPROVED WINDOW-SASH STOP.

T0 ALL WHOM IT MAY CONCERN:

Be it lmown that I, JAMES GREYJEWELL, ofthe city and county ofWashington, and District of Columbia., have invented` a new and improvedMode of asteningWindowSa-sh; and I do hereby declare that the followingisa full and exact description of the same, reference being had to theaccompanying drawings, and to letters of reference markedthereon. i v

The nature of my invention consists in providing a screw-bolt, withsquare nut and cap or handle complete, to be made of' iron, brass,steel, copper, or other metal or composition, which is to be inserted inor on the side of a window-sash, at'the point most desirable, and of therequired length. This insertion is made by boring a gimlet-hole throughthe sash, from exterior to interior, at the side; then cutting a smallmortise through the centre of the sash, midway of the aperture made bythe gimlet; then place the nut in'the mortise square and tight, coveringthe same with a small piece of wood firmly; then pass the screw-boltthrough the nut, until the head or face of the s`crew-boltcomes blui`with the face of the sash; then screw on the cap or handle, tight, orattach the screw-head or pad, (Figures 5 and 6.)` When it is desired tofasten the window at any' height or lower it to any angle, raise orlower the sash, and turn the screw until it presses hard against thewindow-frame and is compact and tight. The sash is then locked, andcannot be raised or lowered unless the fastener is unscrewed. Thisinvention is not only applicable to window-sash, but may beI applied toany desirable sliding panel.

The following will be found to be a correct index to the drawings:

A is the screw with enlarged'head, to press against the window-frame,made either solid, or hollowed out und filled with rubber or suitablesubstance for preventing the abrasion of the window-frame.

B is the screw-cap or handle, by turning which the screw-head is forcedagainst the window-frame. This head or cap is secured to the screw A byanother screw, a.

O is the square nut through which .the screw A passes, and which resiststhe pressure of the screw-head against the window-frame, thereby forcingthe sash over, and securing ,it tightly in any position.

Figure 2. D is the metal plate for attaching to car windows, or wherethe sash is too thin to allow .mortising for the use of a, iig. 1, to bemade with Ltwo or four ilanges or wings, as may bedesired.

`Figure 3. E is the domestic windowsash.

Figurefl. E is the railway-car sash, with thefastener, as applied.

Figure 3. F is the domestic sash, with the fastener attached, showingthe mortise for the scat of the nut, a gimlet-hole being bored from theexterior to the interior of the sash, to admit the screw throughthe'nut.

Figures 1 and 2; a is the screw securing the cap, handle, or button B tothe screw A.

I claim the screw-head or pad A, made hollow, and lled with guttaperche., rubber, leather, composition, cork, or other substance that maybe used for preventing the abrasion of Vthe window-frame.

I claim theibutton or handle, made in one piece with the main screw, andattached to a screw-head or pad by a swivel or shoulder-joint, with asmall screw penetrating the screw-head or pad, as and for the purposeset forth.
